I decided to buy a Nokia E61, downloaded and installed BB Connect, registered the new device and it just worked straight away. Very impressive and hassle-free. I've sold the XDA Exec now as this solution works much better without changing my plan (o2 Blackberry Unlimited). I can also use Mail 4 Exchange on the Nokia too. The only thing is, does anyone know how to set up my work email on my Blackberry account? It is Exchange Server 2003, with mobile extension so I could ActiveSync with with XDA.
